Pioneer Premier DEH p770mp help

I took the unit out of the dash yesterday to wire in Pioneer CD-IB100II iPod interface. once everything was wired up, the head unit no longer turns on. The fuse in it is good, replaced anyways, it didnt pop. I got my volt meter and checked my wires and i have the proper voltages and wires on the harnesses. I have power all the way into the plug that plugs into the head unit.

any one else have any ideas? Oh, grounds are good, clean and strong. 2 14 gauge leads to two different metal braces in the dash.

Make sure all the pins are seated in the harness. Checked both fuses? (Back of the radio, car's fusebox). Ignition input come loose at the crimp? Jumper ignition to constant and see if it will fire up.
